Key capabilities to evaluate:

• WMS with real-time inventory and API connectivity for marketplaces and ERPs
• Efficient pick-and-pack, kitting, and returns workflows
• Temperature-controlled storage and cold-chain handling if required
• Scalable labor models and SLA-backed throughput guarantees

Close access to coastal ports and river transport shortens drayage legs, enables barge consolidation for export, and reduces lead times to coastal gateways. That lowers per-container landed costs and supports more frequent replenishment cycles—important for time-sensitive eCommerce and export flows.

Model these core cost drivers:

• Storage (per pallet/rack) and minimum billing
• Inbound receiving and outbound pick/pack fees
• Transport, drayage, and barge or coastal shipping costs
• Value-added services (kitting, labeling) and customs brokerage fees

Require clear SLAs for order accuracy, on-time fulfillment, and dock-to-stock timelines; KPIs for inventory accuracy and on-time-in-full (OTIF); temperature monitoring for cold-chain; and documented compliance for customs processing, safety audits, and data security. Include remedies and reporting cadence in the contract.
